The $18,400 system, which produces an impressive 3-dimensional display that appears to hover in mid-air, now features native 1024x768 resolution and significantly quieter operation according to the manufacturer. The previous version of the Heliodisplay was limited to native SVGA resolution of 800x600. For $1,000 more, buyers of the new Heliodisplay M3 can opt for a touch-sensitive version of the projector that also acts as a computer input device, providing cursor control in a desktop PC environment.
